Abstract

The environmental factors of the Shatt al-Arab River and the Northwest Arabian Gulf were measured by the YASI measuring instrument. The dissolved oxygen factor in the water was selected as indicator of contamination of the area. Significant differences were observed in the oxygen measurements of water samples in nine stations of the Shatt al-Arab and the Arabian Gulf, with the highest concentration at Shatt al-Arab stations ranging between 8 and 8.8 mg / l. The lowest oxygen value was 5.5 mg / L in the marine fishing area station. The atomic absorption spectroscopy (AAS) was used to measure cadmium and lead in water and the highest value of the two elements in marine waters in the fishing area was 0.076 and 0.999 mg / L respectively.
